iPhone: If you've used an iPhone before, you've probably used one of the many note apps available for it. Some sync, some are focused where others are feature rich, and some are just pretty. NOTE'd manages all three.

The app isn't designed for long-form notes, but rather shorter snippets of text, photos, audio, links, or whatever. You can clip it all together, bookmark anything really important, and categorize it all by notebook. You can see all your notes in a single stream, too. Everything you enter is saved on your iPhone, but you can also have it sync with Dropbox so the notes show up on your other devices. If you don't have any other devices, you can just back up to Dropbox as well. There are plenty of sharing options, and even the ability to lock your notes with a password, but the one thing NOTE'd is lacking is search. That aside, it's one of the best note-clipping apps you can get for a dollar.
